Google Nexus 7 will deliver an even better performance once it gets an update to Jelly Bean 4.2.2 with SentinelROM Build 4.30. We’ll be listing a couple of them now: better and faster browsing, improved battery, a better gaming experience, free copy of My Music Player and more.
ensure that everything goes without incidents, you need to use the Nexus 7 that is bootloader + carrier unlocked, you have to charge the battery of the tablet, create backups using this tutorial (the content of the device’s internal memory should also be backed up to an external hard drive), install USB drivers for this gadget on your notebook and turn on USB debugging.
- First step to kick-off our guide: download the and Gapps package (you must choose the file labelled gapps-jb-20130301-signed.zip) on your PC which will afterwards have to be plugged to the tablet.
- Copy the files to the gadget’s SD card and then unplug it from your laptop. Power the Asus Nexus 7 off.
- Now enter it in Recovery Mode by turning the device on and afterwards return it to its bootloader; now opt for the Recovery Mode with Power after you find it with the buttons for Volume.
- Step four should go like this: operate a NANDroid backup if you haven’t done it for our requirements. This is how to do it: opt for Backup&Restore and choose Backup. When done, return to the Recovery Menu and then perform a wiping action like this: choose Factory Reset/Wipe Data and confirm it by opting for Yes.
- Step number five: return to the Recovery Menu and choose Wipe Cache Partition; once that finishes, opt for Wipe Dalvik Cache.
- Step six will require this of you: opt for Install zip from SD card. Wait a bit until the process ends, then select Choose zip from SD card and then the SentinelROM Build 4.30 custom ROM archive with the help of Power. The flashing of the firmware should now be confirmed.
- Do the same actions you performed for step six to make sure the Gapps package is installed on the tablet next. Make sure both files are flashed on the Nexus 7 and then return to the gadget’s Recovery Mode to opt for the system restarting.
- After you do that, the tablet is going to boot into the SentinelROM Build 4.30. So wait until the Nexus 7 completes this stage of the procedure. The Android 4.2.2 Jelly Bean should now reveal its features and make the user experience better.
Having your Google Nexus 7 updated to an improved operating system can also mean displeasure for the gadget user, in the sense that he or she could want to return to the old ROM. If you wish to do that, boot your Asus Nexus 7 into Recovery, choose Backup&Restore and then restore the ROM by opting for it from a list that will pop on the display.
“Status 7 error” will probably be seen on the tablet’s touchscreen. Do away with it by flashing a compatible kernel on the Nexus 7 and then installing the required ROM. Operate a complete Wipe Dalvik cache and a full tablet’s Wipe cache partition before rebooting the device if the latter experiences a boot loop (or if it remains stuck in boot).
